INDEX.

SPECIFICATION forming part of Letters Patent No. 288,278, dated November 13, 1853. Application filed April 11, 18:55. (No moan.)

To all whom it may concern:

Thisserves to connect the book and index, but in such manner as to enable the index to be slipped upon the eye a to and from the positions shown, respectively, in Figs. 1 and 2. In the position of Fig. 2 the book and index can both be simultaneously opened, as indicated in Fig. 3; The band band eye (1 also form ahinge, upon which the index can turn, enabling either the back I) or the front If of the index to be turned into the book. 'In place of connecting the index immediately with the edge a of the bookcover, the index might be connected with either the top or bottom edge of the bookcover, and at either the back or front of the book.
